Thread: Kennedy Vernier calipers
22/01/2017 15:37:15

I have a set of Kennedy 300mm Digital calipers ref: 331-2320K which I have had for about 3 years now.

They are actually of a decent quality. Cannot speak with any knowledge of the ones you are looking at, but if a set of their 150mm/6" came up at the right price I woould deffo buy them myself and certainly in favour of Mitutoyo who I dislike with a vengence. But thats another long story.

For obvious reasons they never get as much use as my 6"/150mm Tesa digital calipers which are about 20 yrs old now and have been faultless. I have actually bought a set of the M & W from the DRO peple that Neil reviewed recently in MEW. Bought them really to ease the pressure of use on my Tesa. For the £23 I paid for these they actually seem a pretty decent piece of kit but very early days yet.

If I was buying new one it would be the Chester because of two things, their location and secondly colour. I have said it before, quite controversially in that I could not live with their green colour scheme.

What i cannot understand between these two suppliers is why one of them has not taken the lead over the other in offering an " Off The Shelf " 100mm Riser for the column for those that need it, as making you own is time consuming.

By the same ruling Malc I couldn't live with white or cream in a workshop. It is a workshop after all and not a kitchen.

I recently bought a lathe from China from the Sieg Blue and white industrial range and had them paint it all blue to do away with the white. Same for a commercial router that the firm supplied in cream. Told them I only wanted it if it WASN'T in cream, they offered blue so i took it but would have taken any colour.

As regards the risers I can answer this quite easily. I have made 5 or 6 now [ trying to work my way down a eight foot bar of 6" steel ]

Not of them have had the same register and PCD. as it all depends on which factory they are sourced from. 3 of these have been Warco machines, 2 of them from Chester but all of differing ages.

Hi John.

In reverse order, thats very interesting about the risers all being different in hole pitching and registers etc. I have only had to make the one which was quite challenging when I had the Boxy as all i could get my hands on as a freeby was a 170mm dia steel profiled small ID ring. Twas a bit too big for it really.

It dosnt however suprise me about the eastern suppliers having no standardisation. It does not mean though Warco or Chester could not spec them up to now, for them to be standardised and start from there.

Have you had 5 VMC's that you have made so many, or just done for others?

Colours:

Controversial as I mentioned. I can only really go off whats happening in industry, since the early to mid 80's I have put in many CNC machine tools and some specialised machines. Solid green in modern machine tools went out in the late 80's early 90's, the last green ones I put in were Wadkin vertical machining centres.

The emphasis is now actually going beyond that of just a kitchen and more to setting up machine shops that look like laboratories. You only needed to visit Mach 16' to see just how much white is offered. Pale greys, blues etc. The leaning towards a bright but not gaudy CLINICAL look is tremendous.

Personally I love white in machines, it makes a workshop a bright place and it encourages me to keep them clean.

From a small machine tools and traing perspective I was able to join a party of students just before Christmas who were attending the Boxford factory by invite. It was interesting to see their manufacturing and refurbishment facility. Their move to Spacious, tidy, bright and clinical is very evident.

I reckon with both these suppliers that your location could well have a bearing on which machine.

If you are in a relative easy travelling distance to go badger them or procure items quickly then that would be advantageous. Theres little twixt the two machines themselves, maybe the Warco's being finished a tad better, but thats speculative.

I have the Chester 626 which I bought 2nd hand privately and Chester are only about 40 or so miles away which I found useful at first. If it had been badged the Warco I would still have bought it.

If I was buying new one it would be the Chester because of two things, their location and secondly colour. I have said it before, quite contraversionally in that I could not live with their green colour scheme.

But one thing is certain, I would definately buy another VMC as they are so versatile.

What i cannot understand between these two suppliers is why one of them has not taken the lead over the other in offering an " Off The Shelf " 100mm Riser for the column for those that need it, as making you own is time consuming.

I've got a Clarke MIG145. It's not as good as JS's sooper dooper MIG, but after getting the hang of the basic process on the top kit, I was able to get a decent bead with the Clarke one.

Apparently they are much used by hobby car restorers as they will run of a 13A socket.

Must admit, when I'm in a hurry I use the stick welder, which I am almost getting competent at

Neil

Neil, Does your Mig set run on a RCD protected circuit without tripping due to earth leakage, or is it on a none RCD circuit? I am lead to believe that there may be earth leakage that may trip one.

I ask because I have a Clarke 151EN set up for both gas and gassless which I havnt yet got round to using. However i will need to shortly.

I have 13A ,16A and 32A circuits in my garage workshop but they are fed from a RCD protected busbar. Not sure if i will need to get a seperate mini consumer unit sorted for it or not.

Yes. I believe a Colchester Student is more in line with a Harrison M300. From what I can tell, a Harrison M250 is more like a Colchester Bantam. In fact, after the 600 group rationalisation, I think there was a Colchester Bantam that was essentially a Harrison M250 with a different badge and a few cosmetic alterations. I think this is shown on lathes .co.uk.

The latest Harrison M300's and Colchester Student 2500's are also the same lathe as each other. Not shown on lathes.co.uk though.

Slightly off the topic of Dies:

Intrigued by the choice of diameter for these screws; I wondered what might be special about 0.225"

0.225 = 9/40 = #74 Drill size.

Is it feasible that Parker Hale chose to use #74 Drill Rod for its mechanical properties, and close tolerance?

When I worked in the engineering industry I used a lot of tallow, it was particularly good for threading, slotting and shapers. its just stank a bit, we tried all of the early modern tapping lubricants but they were not quite as good as tallow.

Improved on several applications when you gently melted it and added powdered graphite to it before re-solidifying, threading included.

And to open a can of worms, nothing seemed to beat using carbon tetrachloride for low speed threading given its very dangerous toxicity.

I would not let a left handed mounted saddle handwheel be a deciding factor. If you had two similar lathes side by side both in same condition then yes go for RH mounted wheel. In practise there seems to be far more LH than RH though.

I would always go for condition and what " feels right " every time.

The LH mounted handwheel can normally be got round for swarf protection by making up or modifying an existing Swarf guard system to give you good protection from chips.

On my M300 my saddle mounted perspex over guard ( height adjustable ) now drops to around toolpost height. 3M dual lock tape along bottom edge allows me a modular system of add on pieces of 5mm plastic to hang down and give up to full protection as required. Easy to cut piece to protect hand wheel.

I sold my Boxford AUD in last 18 months to go up in size/capacity. Boxfords are great machines if you are OK with 9" or 10" swing but for their high accessory costs.

The later Boxfords with camlock chucks like the industrial series with bigger swings would be well worth considering. Some of these are going for reasonable money.

I was looking for the Bantam 2000 ( the one that had the 6 1/2" - 13" swing ) but they are rarely avalable in any sort of decent condition, so ended up with an M300.

There are far more of the earlier Bantams available of which some are in really good condition. These have a slightly smaller swings and also slightly slower speed ranges on their gearbox than the 2000. Can be sorted with 3 phase inverter setup.

I would also put the Harrison M250 on your list if you can run to them on price.

Then there are far easier to get hold of Eastern manufactured lathes where you get a lot for your money, but sounds like you are not thinking thay way.

Wish you Good luck and hopefully more satisfactory than your recent experience.

You need to download or Purchase a copy of "Know Your Lathe" its a great book dedicated to the earlier Boxfords.

As mentioned, joining Yahoo Boxford User Group is a great asset too. Plenty of very useful downloads to get a grip with.

Thread: An oil gun that works?
03/01/2017 07:06:53

Have a look at the PRESSOL 12362, 12363 and 12365 ( different capacities ) on Ebay alt Amazon.

They are listed as combined high pressure grease and oil and are around the £20 mark inlc postage from Germany on Ebay. They come with two nozzles, one semi pointed and one convex. Use one on my M300 which i easily modified one of the screw off nozzles to suit. Convex is easily usable with just a little O ring. They are well engineered steel telescopic units and seal well at each end. Great value.

If you are feeling really flush then Myford are plugging the WANNER guns at around £75. Wanner have always made really good grease guns.

Hi Hugh,

Good advice would be for you to join the Yahoo Harrison User Group. There are loads of files you can access and download including oil charts. Plenty of other useful info as well.

You can also access and download a pdf copy of the manual, which has the lubrication charts.

Top gearbox is a thin ISO 68 hydraulic type oil. Bottom gearbox I am currently working on grade update comparisons but its an ISO 220.

Think some oil traders on Ebay actually list specific oilsfor the M300. As for Brands, you will never go far wrong if you can get Castrol in economic quantities. The machine capacities are much less than you would think.

As for gearbox rattles i would say that they are never really welcome. There is a few Youtube videos where there have been similar issues which at the end of the day have just been put down to wear and tear with no real cost effective solution. Its an easy job to lift the gearbox lid and check for visible damage, but avoid running with it off as oil will fling everywhere. I would just make sure you are correctltly lubed up if nothing visible is obvious.
